IMPROVEMENT IN DISTILLIN'G SPIRITS QF' URP-E -TiNEQ Specification forming part of Letters Patent No. 7,528, dated July 30, E8 50.

' of Making Rosin Soap; and I do hereby declare that the following is a full and exact de- 1 take a thousand parts of crude turpentine, melt the same, by steam or otherwise, and add eight hundred parts oftullow, greasefat. When both are in a perfect liquid state I stir into them eight hundred parts of liquid soda containing thirty-three percent. of dry pure soda in solution, increasing at the same time the temperature of the compound to 108 centigrade thermometer by passing steam outside the vessel-containing the same. By this temperature the soap is instantaneously termed, lhe'acids constituting the rosin-of the turpentine and thoseforming the grease being perfeetly neutralized by the alkali, and thus eonrerted into liquid melted soap. At the same time the essential oil of the turpent-tizne is setfree, and in order to obtain the same I add asoluiion of common salt of about the same vol-" ume as the melted "soap, connect the vessel containing the whole with a condensing a ppadense the steam arising from it, which carries the essential oil of turpentine withit in the condensing apparatus, which operation is finished in a short time, the spirits being already setl'ree by the action of the alkalhus menf tioneil above. In this manner I do obtain two articles of manufacture with one expel lse for fuel and labor, which products, when made separately, as now practiced by soitp-makors and turpentine distillers, cost more time-end more expense. "When all the essential oil is distilled over the remaining soap is finished- I practiced by all in a manner and style now manufacturers of soap.

What I claim as my iuv'ention, and desire.

to secure by Letters Patent, is-' The process, as described, for distilling turpentine, so that the spirits of turpentine are" distilled and the rosin saponified ready for soapmaking at one operation. A
